1. An electronic module comprising:
a mold body in which an electronic component mounted on a circuit substrate is sealed by a mold resin; and a shield film formed to cover upper and side surfaces of the mold body, the shield film being a metal evaporated film formed by physical vapor deposition, wherein the circuit substrate includes a ground pattern which is formed so as to be exposed at a side surface of the circuit substrate except for vicinities of corner portions of the circuit substrate, wherein the shield film is connected to the ground pattern at the side surface of the circuit substrate except for the vicinities of the corner portions, wherein the circuit substrate is a multilayer substrate and includes a via exposed at the side surface of the circuit substrate and connected to the ground pattern, wherein the shield film is formed to contact the via at the side surface of the circuit substrate, and wherein the via and the ground pattern are formed so as to be exposed at the side surface of the circuit substrate except for the vicinities of the corner portions.
